Embodiment 1
[0052] The main steps of the production process of this pink glass are as follows:
[0053] (1) The raw materials are proportioned according to the following parts by weight: SiO 2 65.00 copies; Na 2 O 4.50 copies; K 2 O 12.15 copies; B 2 O 3 2.50 parts; PbO 15.60 parts; SnO 2 0.25 parts; Au 0.0075 parts.
[0054] (2) Mix the various raw materials uniformly according to the required proportions, and put them into the crucible for melting glass at 1200°C. The clarification temperature of the glass is controlled at 1400°C, and the clarification time is 4 hours. During the clarification of the glass, the glass is constantly stirred.
[0055] (3) After the glass is cast and formed, it is immediately put into an annealing furnace for annealing, and the annealing temperature is controlled to 470°C.
[0056] (4) Expose the prepared sample to ultraviolet light for 10 minutes, and keep the distance between the lamp and the sample 10 cm.
[0057] (5) Put the irradiated sample into a resista...
Embodiment 2
[0059] The difference from Example 1 is that the raw materials are proportioned according to the following weight parts:
[0060] SiO 2 70.06 copies; Na 2 O 17.32 parts; BaO 8.36 parts; PbO 2.60 parts; B 2 O3 0.50 parts; Sb 2 O 3 1.15 parts; Au 0.01 parts.
[0061] The difference from Example 1 is that the sample is exposed to ultraviolet light for 30 minutes, the heat treatment temperature is 600° C., and the heat treatment time is 60 minutes.
Embodiment 3
[0063] The difference from Example 1 is that the raw materials are proportioned according to the following parts by weight:
[0064] SiO 2 65 parts; Na 2 O 5 copies; K 2 O 14 parts; PbO 15.6 parts; Sb 2 O 3 0.40 parts; Au 0.01 parts.
[0065] The difference from Example 1 is that the sample is exposed to ultraviolet light for 3 hours, the heat treatment temperature is 650°C, and the heat treatment time is 60 minutes.

Abstract
The invention discloses a formula of pink glass and a process for preparation thereof. Mainly the components of raw materials percentage by weight of the pink glass comprise: SiO2 holding 60-75 parts, Na2O and/or K2O holding 16-20 parts, PbO holding 2.6-20 parts, SnO2 or Sb2O3 holding 0.25-1.15 parts and Au holding 0.005-0.1 parts. The pink glass is prepared by uniformly mixing various raw materials as proportionally required into mixed material to charge in a corundum crucible and smelting by placing in a furnace, and after molding and forming of the glass, immediately placing in an annealing furnace for annealing with the annealing temperature controlled within 450DEG C-500DEG C. Then the glass is lighted in ultraviolet light for 1minute to 10 hours, performing heat treatment at a temperature of 550-650DEG C till the time when the glass generates expected pink color. The invention is easy in manufacturing technique and operation process and easy in controlling color and the prepared glassware has the advantages of uniform coloring, high refractive index, beautiful color and stable quality, gold coloring agent is low in consumption, thereby largely reducing production cost, and the invention is adaptable to industrialized production.
Description
Technical field [0001] The invention relates to the field of glass production, and mainly relates to a formula of pink glass and a preparation process thereof. Background technique [0002] Pink glass is a kind of precious artistic glass products and glass jewelry manufacturing base. The preparation of pink glass is more difficult. The current pink glass basically uses gold as the colorant of the glass. The amount of gold is relatively large and the cost is relatively high. The basic composition, melting process and heat treatment color of glass are of great significance to the production of golden red glass. The coloring of gold glass belongs to colloidal coloring, which can produce beautiful and elegant colors after color development, and control the size of metal colloidal particles, presenting purple-red, blue, etc., and is often used to prepare high-end crafts, high-grade ware glass and decorative art glass Wait. [0003] Although the research on gold-red glass began in the ...
